My bot found errors running 'make DT_CHECKER_FLAGS=-m dt_binding_check'

This check can fail if there are any dependencies. The base for a patch
series is generally the most recent rc1.

If you already ran 'make dt_binding_check' and didn't see the above
error(s), then make sure 'yamllint' is installed and dt-schema is up to
date:

pip3 install dtschema --upgrade

Please check and re-submit.

+description:
+  The MediaTek MDP RDMA stands for Read Direct Memory Access.
+  It provides real time data to the back-end panel driver, such as DSI,
+  DPI and DP_INTF.
+  It contains one line buffer to store the sufficient pixel data.
+  RDMA device node must be siblings to the central MMSYS_CONFIG node.
+  For a description of the MMSYS_CONFIG binding, see
+  Documentation/devicetree/bindings/arm/mediatek/mediatek,mmsys.yaml for details.
